Description

This perl script will provide grep-like functionality to return multi-line (record) matches for

blank-line deliminated files such as LDIF files used by LDAP. A match on any line will return

all lines from the previous blank line until the following one.

here this is the script

----------------------------------------------

#!/usr/bin/perl -w

use strict;

my $search = shift;
my $file = shift;
my $out = shift;
if (! $file)  {
        open(INF, '-') or die("Unable to open STDIN\n");
} else {
        open(INF, $file) or die("Unable to open $file\n");
}

my @buffer;
while (<INF>)  {
  my $line = $_;
  if ($line eq "\n")  {
        my $count = 0;
        #@buffer = "";
        undef @buffer;
  } else {
        $buffer[$#buffer+1] = $line;
  }
  if (/$search/io)  {
        my $buf;
        foreach $buf (@buffer)  {
                print $buf;
        }
        while (($out = <INF>) ne "\n")  {
                print $out;
        }
        undef @buffer;
        print "\n";
  }
}
